Abstract (en)

[origin: WO2010036529A1] The service life of amperometric electrochemical oxygen sensors is increased by operating the electrodes of such sensors at a polarization voltage suitable for measuring the oxygen content of samples only during calibration or when measuring such samples and thereafter modulating the polarization voltage to a lower voltage such that substantially no electrical current is produced by the electrodes.
